To get the sister directory path in Java 20, you can use the getParent() method on the File class. This method returns the abstract pathname of the parent directory of the file or directory represented by the File object.
Here is an example code snippet to get the sister directory path in Java 20:
import java.io.File;
public class SisterDirectory {
public static void main(String[] args) {
// Specify the path of the file for which you want to find the sister directory
File file = new File("/path/to/your/file");
// Get the parent directory of the file
File parentDir = file.getParentFile();
// Get all directories in the parent directory
File[] subDirs = parentDir.listFiles(File::isDirectory);
// Find the sister directory by excluding the directory with the same name as the file
File sisterDir = null;
for (File subDir : subDirs) {
if (!subDir.getName().equals(file.getName())) {
sisterDir = subDir;
break;
}
}
// Print the sister directory path
if (sisterDir != null) {
System.out.println("The sister directory path is: " + sisterDir.getAbsolutePath());
} else {
System.out.println("Sister directory not found");
}
}
}
In this example, we first specify the path of the file for which we want to find the sister directory. We then get the parent directory of the file using the getParentFile() method. We get all directories in the parent directory using the listFiles() method with a filter that only selects directories. We then find the sister directory by excluding the directory with the same name as the file. Finally, we print the sister directory path.
